    <!--

    Adds a CI job that checks each workspace crate individually (`cargo
    check -p <crate> --all-targets`),
    catching missing feature declarations that are otherwise masked by
    Cargo's feature unification
    across the workspace.
    
    ## Are these changes tested?
    
    <!--
    Specify what test covers (unit test, integration test, etc.).
    
    If tests are not included in your PR, please explain why (for example,
    are they covered by existing tests)?
    -->
